1 Claims. (Cl. 164-73) This invention relates to newand usefulimprovements in edging tools.

One object of the invention is to provide an improved edging tool formarking or scribing linoleum, or other similar floor covering, so thatwhen the linoleum is out along said marking it will fit snugly-along thewallet the room. 7 Another objectof the invention is to provide animproved edging'tool which includes a [curved ing, it will snuglyfitfagainst the wall of the room.

' An important object of the invention is to providean improved edgingtool for cutting linoleum and the like, in such a way that said linoleumwill fit snugly against the wall of the'room wherein it is laid.

A further object of the invention is to provide an improved edging toolfor marking or scribing linoleum or the like, which has adjustable guidemeans for engaging the wallet the room to guide said tool during themarking operation.

'Still another object of the invention is to provide an improved edgingtool for marking or scribing linoleum, or other similar materialwhichincludes a slot which receives the linoleum to be cut, the slot beingadjustable in width so as to receive linoleum, of various thicknesses.

A construction designed to carryout the in: vention will be hereinafterdescribed, together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawing, inwhich an example of the invention is shown, and wherein: n v

Figure lis' a side elevation of an edging tool,

constructed in accordance with the invention.

Figure 2 is an enlarged sectional view, showing a cutting disksubstituted for the stylus.

Figure 3 is a transverse sectional view, taken on line 3-3 of Figure 2.

In the drawing, the numeral Ill designates a frame member which formsthe main supporting element of the tool. The frame includes a verticalside H and a horizontal base l2. The rear of the frame is formed of anarc l3 which is preferably made integral with and curves downwardly fromthe verticalside II. A roller 14 is mounted in the base [2 and serves tosupport the ,as to ride in the corner formed by the intersecrear of theframe. A suitable guide roller I5 is carriedby a horizontal bar i6 whichis mounted at the forward end of the base; The bar I 6 is provided withan elongated slot Iii. Bolts I! pass through the slot and through thebase 12 and re- 5 ceive thumb nuts l8 on their upper ends. It is obviousthat by loosening the nuts Hi, the bar l6 and the roller it carriedthereby may be adjusted with relation to'the frame. It ispointed outthat the entire frame is carried by the rollers l4 and, 10 [5. Asuitable handle 58 is provided in the frame 10.

A curved slot 19 extends from the lower end of the rear side of theframe; and is curved upwardly terminating at the forward endof the Iframe near the upper'e'nd thereof. The bottom of theslot is formed of acurved swinging member 20 which' is pivoted at its lower end at 2|. Anadjusting'screw 2'2 threaded in a boss 23 on the frame has its upper endjournaled in the swing- 20 mg member 2% whereby rotation of the screwwill swing said member. It is obvious that by adjusting the screw .22thewidth of the slot may be controlled. 7

A stylus 24 is mountedin the frame and has its 25 pointed end extendinginto the slot I9. The stylus is adjustably 'mounted in a bearing 25which is slidable through a boss 28 in the frame.

The bearing 25 has a rod 26 integral therewith and the outer end of saidrod extends through a 30' boss 21 on the are iii of the frame. A spring28. surrounds the rod and it is confined between the boss 2'! and anadjusting nut 29 which is threaded on the rod 26. It'is obvious that thespring serves to hold the stylus well within'the slot, the ten-; sionofsaid spring being varied by the adjusting nut 29.

In laying linoleumA or other fioor covering its has been found that itisdifficult to cut the linoleum A along a line so that said linoleum 40will fit snugly in the corner formed bythe intersection of the floorwith the wall. By providing the above described tool such correctmarking is readily obtained. In using the tool the linoleum A is cut towithin an inch or two of the point 5 where it must actually be out tofit the fioorperfectly. This cut end is then inserted into the slotcurving upwardlytherein as shown in Figure 1. The guide roller i5 isthen positioned so tion of the floor and wall. When the tool is in thisposition the distance from the lower rear end B of the frame it) to thepoint C where the stylus engages the linoleum within the-slot I9 is thesame as the distance from the point B to the corner D formed by theintersection of the wall and the floor. Thus by moving the tool alongthe wall keeping the guide roller at the point D the stylus will markthe linoleu 1 along the exact point where it is to be cut. If it isdesired to loosely fit the linoleum the guide roller I 5 may be movedforwardly of the frame by loosening the nuts [8 and moving the bar l6forwardly. If the intersection between the wall and the floor is curved,as it is in some cases and as shown in dotted lines in Figure l, theguide roller I5 may be retracted at the dotted line shown in Figure l,and the tool may be guided by a small roller which is carried byan'adjustable bracket 3| which is threaded in a boss 32 in the lowerforward end of the frame. The roller 36 engages the Wall of the roomabove the corner D, and it is clear that said roller will serve as asuit able guide.

From the above it is obvious that the stylus will mark'the linoleum onthe line where it is to be cut but it is possible to substitute acutting disk 33 for said stylus as shown in Figure 2. Thus when the toolis moved along the wall the disk would cut the linoleum along thedesired or correct line. This would obviate the necessity of cutting thelinoleum by hand after it had been marked.

The advantages of the tool are obvious. It is only necessary to insertthe linoleum in the slot l9 and draw the tool along the wall of theroom. By adjusting the tension of the spring 28 the depth of the markingis readily controlled. As the tension on the spring becomes Weakertheadjusting nut 29 may be tightened. The adjusting of the guide roller[5 provides for variation of the line of marking and the adjustabilityof the width of the slot l9 provides for accommodating linoleum ofvarious thicknesses. The tool is :simple and compact in construction andmanu facturing costs are held to a minimum. The stylus 24 is the onlypart which receives any amount of wear and this is readily replaced andadjusted.
